What the trial is, and whether it could suit you
The prognosis of locally advanced oral squamous cell carcinoma(OSCC ) is poor, and there are still many problems to be solved in the current treatment paradigm. Neoadjuvant chemotherapy combined with immunotherapy can significantly improve the pCR and MPR rates in patients with locally advanced OSCC. For patients who achieve pCR and MPR after neoadjuvant therapy and surgery, it is still hotly debated regarding whether to implement postoperative de-escalation radiotherapy. Neoadjuvant therapy is an ideal predictor of radiosensitivity. In theory, neoadjuvant therapy can eliminate microscopic lesions, thereby reducing the dose and volume of irradiation.
Continuous hyperfractionated accelerated radiotherapy (CHART, based on hyperfractionated radiotherapy, increasing daily or weekly treatments and shortening the total treatment duration, but reducing the total dose), is to give a higher dose
